T all wlwmit mm] canoe-m:

Be it known t at I, ZEBUDDN V. KEN- nnrcK, a citizen of the United States, residing at Charlotte, in the county of Mockle-nlmrg and State of North Carolina, have invented certain new and useful Improvements in an Automobile Lift, of which the following is a full, clear, and exact descripill-O11.

One object of my invention is to provide a sim do and efficient mechanism for lifting and tilting an automobile so that access to its: under side may be rendered eas thereby permitting repairs, painting oi g and the like to be performed convenlentl The mechanism mu also be used for disp y purposes when it IS desired to expose the arts hidden beneath the body 0 the machine.

Another object is to provide a mechanism of the character described which will be portable and self contained, and which may be located wherever a substantially level space is; available, requiring no particular foundation or previous construction work for its employment.

Uther objects will be apparent from the following detailed description and appendcd claims.

in the drawings:

Figure l is a perspective view of the device in operated position, with an automobile indicated in position thereon.

Figure 2 is a top plan view of one oi the elevating devices tor raising the automobile with its adjacent parts. v

Figure I! is u vcrticn section of a difierout form of elevating mechanism.

Figure 4 is a side elevation of nism shown in Figure 3.

Figure is a side elevation modification.

Figure 6 is a perspective view of a portion of the structure shown in Figure 5.

The device comprises base members 1 which may be refcrably T-shaped angle irons and are adapted to rest on the floor,

disclosing a ground, or any suitable support. Transverse sup orte 2 are pivoted at 8 to the base members at an appreciable distance from one end. 'lhese supports are each preferably constructed as a air of angle irons, adapted when in norm ositlon to fit, one

on each side of the vertical rib of the T- shaped base members. The two angle irons the meclia- -by ball beari each support 2 are clearly shown in lgures 3 and Carried by the transverse supports 2 are longltudmall extending track members 4 which have locks 5 on their under sides near the middle thereof, furnishing an additional support therefor when in normal positlon. These track members have outwurdly and downwardly flared ends 6 enaiding the wheels of an automobile to be positioned thereon with ease.

Pivoted at ,7 to the o posits end of each base member 1 is a me mally occupies a substantially vertical position but can move about its pivot as the device is operated. Attached to the outer end of the support 2 is a bracket member 9 having an opening in which the ci rocates, and a roller 10 en ing the back 0 the bar to guide it and facilitate its movment. The rack bar is engaged by a pinion 11 on a shaft 12 which carries a worm car 13 engaging with a worm 14 on a aha 15 provi c with a handle 16. It is obvious that turning the handle 16 will, through the wormgearing, turn the pinion 11 and cause it to travel along the rack bar thereby raising or lowering the frame'with the automobile A thereon.

As shown in Fi res 1 and 2, the mechanism 'ust describe may be attached to the and 0 each support 2, and two men will be crate the device conveniently.

necessary to 0 Figures 5 and 6, the

However, as s own in lifting mechanism me be arr d to be operated by one han le. In this case a bevel gear 17 is mounted on each shaft 15. Mounted in arms 18 projectin from the bracketsiliaashaft 19 carrying vol gears 20 at its ends that mesh with the era 17. One handle 16 may therefore be fispensed with, since the motion of one shaft 15 is transmitted through the bevel gears to the Ether shaft 15, an one man may operate the once.

An alternative form of operating mechanism is shown in 8 and 4. 1 Instead of the rack bar 8 there is employed a threaded shaft 8",which is ivoted at its lower end tothe member 1. travelling nut 21 is mounted on the threaded shaft and supports 22 a sleeve member 23 which has int bracket 9 t at takes the place of the bracket 9 in the first construction. Fastened by set cs 24 on which is pivoted a bar .8 which nora rack bar reect considerably disclosed in Figures 5 overturning when-lifted to or screws 25 to the upper end of the travelling nut 21 is a bevel gear 26 and ball beari 27 are provided at the point of contact 0 the nut 21, sleeve 23 and bevel gear 26. Also carried by the sleeve 23 is a bevel gear 28 mesh with the bevel gear 26 and rovided with ai iandle or crank 29 by whic it may be turned. An operation of this crank will result in a taming of the bevel gear 26 and a corresponding rotation of the nut 21 which produces a trave g movement thereof and raises or lowers the frame.

The modified formeof mechanism shown in Figures 3 and 4 may be substituted either in the structure shown in Figures 1 and-2 where two cranks are necessary, or in that crank is employed.

Any desired means ma be emfiloyed for fasteni the automob'e' to t e lifting frameffiut I prefer to use one or more chains 30 having hooks 31 at each an interposed turnbuckle 32. One hook is hooked over any suitable part ofthe chassis, the chain passed around the lozigitudi-nal member 4! and -hooked on itself. t is then ti htened by the turnbuckle as desired.

It is noted that the base members 1 probeyond the pivot points .3 where the supp rts 2 are attached thereto. This, obviates any danger of the'machines beyond the position shown in Figure 1.

The various frame members are fastened together with bolts, and the devtice is there fore easily taken apart for transportation or storage. with the exception of the castmg containing'the ar mechanism, all arts are preferably ma e of steel, and are t ere fore strong and durable. 7
